The said 3 5 I11 OM01 that Said illVPlllVlOll ybe top carriage is so formed at the upper end of clearly understood andreadily an'ried into 11 5, h h -i as to limit the training effect, wewill describe the same more fully movement, for which purpose the upperend with reference to the acconu ny ng of the cylindrical portion 71"has a stationary ings, in whicl plate 7) formed with segmental slots 1/,Fig.

40 Figure 1 is a side elevation of a tripod- 3, for the reception ofdepending lugs c of mounting furnished with our improvements, a plate0", adapted to turn with the boss or the said figure representing thegun and bearing 0'. The parts are kept in place upon h'lounting in theirfiring position. Fig. 2 is the cylindrical portion 7)" by a screw 7):,pro- 0 a vertical section, and Fig. 3 a plan, showjecting upwardcentrally from the said cy- 5 ing on a larger scale the top carriage andlindrical portion 0 and having a nut 72" and traversing plate and theportion of the trail also spring-washers If" to prevent or minithatcarries the same. Fig. 4: is a sectional mize slackness or play at thepivot. The

a'loresaid arm carries a clamping-screw c and nut whereby the topcarriage and traversing plate :an be locked to and released from eachother, the traversing plate having in it a slot 0', Fig. 3, wherein thesaid screw can move to permit oil? the necessary lateral adjustment ofthe top carriage relatively to the plate, either the nut or the screwbeing provided with a handle or lever tor tightening or slackening thesame. In the drawings the. nut c is provided with the handle. \Vhenreleased,'the said top carriage, together with the gun, can be freelyturned by hand about the vertical pivot to quickly traverse the gun toany required position. V

For the accurate or fine training or traverse ot the gun we provide ator near the end of the traversing plate a rectangular longitudinal recc, in which is fitted the die or holder c" of the nut 0 ot thetraversing screw 0, which screw extends along a transverse slot oraperture 7) formed in the traversing segmei'it. In this transverse slotor aperture the said nut is caused to travel to the right or left bytheaction of the screw operated by the hand-wheels 0, thereby moving thetop carriage in the required direction tor the lateral training ortraversing of the gun. The said rectangljllar recess a is somewhat.longer than the die 6, so that the latter as the nut c moves along thesaid slot or aperture. will have su'llicient freedom in the said recessto permit the nut during the circular movement of the traversing plateto follow the rectilinear direction due to the revolution ot thetraversing screw.

It will be seen from the above description that when the clan'ipingscrew or bolt 0", which locks the top carriage to the "traversing plate,is slackeued the gun and top carriage can be moved togetherindependently of the traversing plate and quickly turned either to theright or left about its vertical pivot by the pressure of the handalone, thus a tl'ording the means for immediate rough laying of the gun,whereas it fine or accurate laying be required the clamping-screw a mustbe tightened to lock the said top carriage to the traversing plate, andthen the gun can be trained by the hand-wheel. c of the a toresaidtraversing screw on either side of the trail.

In preparing the said mounting for transport the trout legs b can beturned to a forward position and adjusted in linewith the rear leg ortrail 2'), as represented by the dotted lines on the right-hand side ofFig. 1. The rear leg or trail is provided with lateral handles 7), oneon each side, so arranged that four men can assist in carrying the said.mounting. The tripod can be easily folded to term a compact loadsuitable for pack transport by turning inwardly the legs L into aposition alongside the trail 7), as shown by the dotted lines in Fig..1, the gun. being in the latter case removed from the top carriage.

A seat Z) is provided on the trail in a convenient position. for the useoi? the gunner or firing-immber when firing the gun.

Although we have shown our improvements applied to a tripod stand ormounting, we wish it to be understood that they ari applicable to anyother mounting or carriage in which the gun is mounted in a pivoted lopcarriage substantially as above described.

- \Vhat we claim, and desire to secure by Letters Patent of the UnitedStates.

1. In a gun-mounting, the con'ibination of a top carriage in which thegun is trunnioned, a pivot on the mounting about which the top carriageturns in its training movements, a traversing plate movable about thesame pivot as the top carriage, traversing mechanism for actuating saidtraversing plate, and means whereby the top carriage can be moved eitherii'ulependently ol' the traversing plate for rough training by the handor simultaneously with the traversing plate ilior fine training by thetraversing mechanism.

2. In a gun-mounting, the con'ibination of a top carriage in which thegun is trunnioned, a pivot on the mounting about which the top carriageturns in its training movements, a traversing plate movable about thesame pivot.as the top carriage, traversing meclmnism tor actuating saidtraversing plate, and a clamp for readily locking or unlocking the topcarriage to or from the traversii'ig plate for the purpose specified.

In a gun-mounting, the combination of a top carriage in which the gun istrunnioned, a pivot on the mounting about which the top carriage turns.in its training move ments, a travt-zrsing plate movable about the samepivot as the top carriage, traversing mechanism for actuating saidtraversing plate, a clamping-screw carried by the top carria andprojecting through a segmental slot in the traversing plate, aclamping-nut on said screw, and a. handle ilior actiutting said nutsubstantially as and for the purpose specified.

41-. In a gun-mounting, the con'ibination of a top carriage in which thegun is trunnioned, a rearwardly-extending arm forming part of said topcarriage, a vertical pivot on the mounting about which the top carriageturns on its training movements at traversing plate movable about saidvertical pivot and situated immediately below the top carriage, a.transverse screw rotatably carried by the mounting, a nut on said screw,a holder for 'said nut fitting in a longitudinal recess in thetraversing plate, means for acti'iating said screw, and means wherebythe top carriage can be moved either independently of or sinnIltaneouslywith the traversing plate for the purpose speoitied. V

5, In a g'ui'i-mounting', the combination of a top earriage in which thegun is trunnioncd, a rearwaidly-extending arm on said top carriage, avertical pivot on the mounting about which the top carriage turns in itstraining movements, at tra\ *ersing plate movable about said verticalpivot and' situated immediately below the top carriage, a slottedstationary segmental traversing segn'ient. supporting the rear end ofthe traversing plate and the rear end of the top carriage, a transversescrew rotatably earried. by said slotted traversing segment a nut onsaid screw, a holder tor said nut fitting in a longitudinal reeess inthe traversing plate, means for actuating said screw, and means wherebythe top earriage can be moved either independently of or simultaneouslywith the traversing plate substantially as and for the purposespecitied.

(3. In a gunanounting, the combination of a top carriage in which thegun is trunnioned, a vertical pivot on the mounting, a c, lindric,albearing on the top carriage fitting around said pivot, a traversingplate, a evlindrieal bearing thereon also fitting around said pivotbelow the bearing of the top carriage, a collar on the n'lountingsupporting said superposed bearings, a coverplate located above thebearing of the top carriage and movable therewith, depending lugs onsaid cover-plate, a stationary plate situated beneath said cover-plateand having segmental slots for the reception of the depending lugs, ascrew and nut for retaining said cover-plate and stationary plate on thelnonntii'ig, a spring-washer interposed between the cover-plate and thenut, and a clamp for readily locking and unlocking the top carriage toand from the traversing plate substantially as and tor the purposespecified.

In testimony whereof we have herei'lnto set our hands, in presence oftwo subscribing witnesses, this 1st day of M arch, 1905.
